I think there are a few options available. Some of those would require legislation. The Public Health Agency of Canada was born out of the SARS Commission and a recognition that we did need a strong federal response to infectious diseases and pandemics. Over time, PHAC has seen its budget and its overall strength diminished by effective reductions in budgets, etc. I think that's one aspect of it.
The second thing I would say is that NACI has proved itself to be an efficient structure and organization for immunization practices. It has effectively advised provinces that have then contextualized the advice from NACI. I don't see why a similar approach—whether it's therapy for infectious diseases or overall strategies to tackle infectious diseases—can't be structured in a similar manner.
